Quiet system, big overclock

ABIT IP35 Pro LGA 775
8800gtx
quad q6600 GO
Western Digital Caviar SE16 WD7500AAKS 750GB
Westinghouse L2410NM Glossy Black 24"
Thermalright HR-03 plus
Thermalright Ultra-120 Extreme
Using 2 sflex case fans for heatsinks and 2-3 noctuas for case cooling.
Probably a 5.25 hard drive case, don't know much about them though.
Corsair 520 or 620
6ch zalman fan controller

I'm looking for a pretty quiet system, around 20-25db that I can overclock A LOT.

For a case I am thinking a 182 but I'm worried about cooling. Could a 182 get me above 3.5 with reasonable temps? Around 50C load.

Would a corsair 520 be enough for system including a big voltage increase?

Looking for ram under 200 bucks that overclocks well. 2 gigs 2x1. I was maybe thinking crucial but I know little about memory overclocking.

Also with the hr-03, will hot air pool up at the bottom of the case?, how could I solve this besides a major case mod (Like slicing up my case).

3.5 Is a big o/c on air.. I'm not sure anything is going to get you those speeds at 50c or lower. Heck, my (admittedly poor) cooling solution with B3 Q6600 idles at 46-48c, and will be a touch louder than your target 20-25DBa.

50C load with a G0 on air is tough. you'll be lucky for mid 60's. you're starting a 95W TDP, and you're taking it much higher, so you might idle near 50 unless you go with massive airflow solutions.

i'm not saying its impossible, however i don't believe its as possible as you want [or anyone]

why would you want such a high OC though? wouldn't a quad core be more than enough as is? unless you're doing CAD work or something, its almost pointless, most apps hardly touch 2 cores as is.

Well I would definitely not overclock it that high right when I get it. I am thinking of going that high when I have had it a couple years. Anything above 3 is not needed a whole lot anyways since I will have a gtx. I just want to have the system that I can get that high with later on. What is a case that cools very well but is still pretty quiet? Also I'm still stuck on ram. And with hr-03 plus airflow.

Hi,

I got the same setup Q6600 GO @ 3600 (1,4v) + U120e with 2 nexus @ 600rpm + IP35 pro and I get ~ 40Â° idle and low 60Â° full load, but I don't have a case so it should help for the temp (amb tÂ°=22Â°c))

This is pretty silent

You're going to be working the psu pretty hard with an overclock like that combined with the 8800GTX. I'd definitely recommend a case where you can completely isolate the psu such as the P182. You need low intake temps to keep the psu fan from ramping up.

I think the Corsair 520 could handle just fine with probably 150+ watts of overhead space left.

Looks like a good plan so far. Don't forget to remove the expansion bay covers below the GPU, and possibly mount a fan down there to encourage airflow. Those temps might be possible, but you will need to keep the case temps as close to ambient as you can.

I had an idea about the hr-03's airflow that I posted here. viewtopic.php?t=43790

What do you think? I know this would probably stop hot air from pooling up but would it hurt/help/not affect the ultra 120 and cpu temps?

If you aren't going to manage the airflow beneath the card, putting the HR-03 above the GPU is an obvious choice. Of course, there will still be a heat issue from the other side of the card. My first thought would be to keep it on the bottom and put fan right next to it along the vacant slots.

An interesting idea would be to make this an intake fan; giving the GPU fresh air directly from the outside. The P180 has twice the exhaust as intake in the main chamber, and this would even things out. Some hot air might be recirculated from the PSU, but a small baffle would be easy to put in.

I will need to use 1-2 pci slots below the vid card, what would be the biggest fan I could put there?

ddrueding1 · Post by **ddrueding1** » Thu Oct 04, 2007 2:53 pm

Ugh. Perhaps an 80mm, but I would instead consider putting a 120mm fan at the front of the GPU pulling air along the card; possibly with some ducting to be sure it is fresh. This is even more important if you have other PCI cards in there.
